To all whom it may concern:

Be it known that I, WILHELM ARnnrrANN, a citizen of the German Empire, residing at Hamburg 22, Germany, have invented certain new and useful Improvements in Apparatus for Removing and Applying Coats of Pitch and the like to Casks and the like, of which the following is a specification.

This invention relates to apparatus for use in treating casks and the like for the purpose of. removing a coating of pitch or some similar coating by heating same, and also for applying a fresh coat of pitch or similar coating.

The object of the invention is, in the first place, to provide a simple continuous apparatus for removing the coating and for applying a fresh coat to the interior of the cask or like receptacle.

A feature of the present invention resides in the provision ofmeans for transporting the cask intermittently and for raising the cask at one stage in its transportation, both these means being operated alternately by a common driving member. The mechanism employed for this alternate intermittent movement preferably comprises two spur or like wheels having radial slots therein which are alternately engaged bya rotating pin carried by a crank. The heating furnace which. supplies the hot gases for removing the coating of pitch is conveniently fixed rigidly and caused to move with the apparatus for removing the pitch from the casks.

Generally speaking, the apparatus comprises a rotatable table which moves with a step-by-step intermittentmovement and is provided with supports for the casks. In the neighborhood of the supports, hot air nozzles are provided which are supplied with hot air from acentral furnace which rotates with the table. At a desired point in the movement of the table an elevating arm engages with each of the casks to lift and remove the same from their supports and place them over a nozzle by means of which pitch or like substance is sprayed to forman internal coating.

The invention thus outlined roughly will be more readily understood from the following particular description made with refer.

'8 oil' or similar'fuel circulates. 'o'oils open lnto a burner chamber 9 from vating arm. Fig. 3 is a side elevation. of

the elevating arm and its operating mechanism. Figs. 4 and 5 are detail views of operating parts which effect the coating ofthe cask. Fig.6 is a general plan of the trans- -porting parts of the apparatus shown in Fig. 1. Fig. 7 is an enlarged View of part i of the elevating arm while Fig. 8 is an enlarged sectional View of the air and gas supply connections to the furnace.

. In carrying the invention into effect and referring more particularly to Fig. 1, the furnace l, is composed of a cylindrical vessel lined with a thick coating 2 of a suitable fire proof material, such as fire clay. This coating leaves a central duct 3 which opens at the upper end into a widened chamber 4. The furnace is mounted so as to rotate about its vertical axis,'being supported to this end on a circular track 5 by rollers 6. Two coils 7 and 8 are embedded in the fire proof lining 2. The coil 7 is destined for the circulation of air while-through the coil which the flame passes to the central chamher 3 of the furnace. The coil 7 communicates with an axially disposed pipe 10, while the coil 8 communicates with a pipe 11. The pipe 10 opens into a stufi'lng box 12 so that this pipe is able to rotate while the pipe 13 communicating with the other end of the stuffing box remains stationary. The pipe 13 supplies the air. The pipe 10 is surrounded by a fixed casing 14.- and the casing is rendered air tight with reference to the Both the rotating pipe 10 by the aid of a stufling box 15.

The upper open end of the fixed chamber 14 (see Fig. 8) is closed by a plate 16 which is rigidly connected and rotated with the pipe .10, The plate 16 is convenientlyproformed by the casing 20. The box or trough 22 in the casing 20, is removable and the casings 20 are connected by an annular cover or. frame 23 arranged directly over the waste trough 24 which receives the pitch or like substances removed from the barrel. The

main driving shaft 25 is suitably provided with a worm wheel or the like 26 engaging with a corresponding wheel 27 on a shaft 28 supported in bearings 29; On the shaft 28 1 there is mounteda crank 30 having a .pin 31.

Parallel to the shaft 28 there are provided two shafts 32, 33 (see Fig. 2) each of which carries a gear wheel or ratchet disk 34 or 35. Each ofthese disks is provided with a suitable number, for instance twelve, radial slots 36 and 37. In this way when the crank 30 rotates continuously the crank pin 31 alternately engages first in one of the slots 36 of the disk 34 and then in one of the slots 37 of the disk 35. When the pin 31, Fig. 2, rotates clockwise, the disk; 34 is rotated through a certain angle in the direction of the arrow 38, while the disk 35 is rotated in the direction of the arrow 39.

On the shaft 32 there is mounted a gear wheel 40 which engages with a pinion 42'on the rotatable shaft 41. On this shaft 41 there is mounted a beveled wheel 43. The

' bevel wheel 43 engages with a bevel wheel 44 on the shaft 45. On. the shaft 45 the driving pinion 46is mounted which engages with the toothed ring 47 rigidly fixed to the furnace. It will be seen that as soon as the pin 31 in its clockwise rotation completes its first half revolution, through 180, the disk 34 is rotated through such an angle that the cask 48, Fig. 6, is moved from the position 48, into the position 48 On the shaft 33 (Fig. 2;) there is mounted a gear wheel 49 which engages with a gear wheel 50 on the shaft 51 (Fig. 1). The shaft 51 carries a wheel 52, which in turn engages with a wheel 53 on the shaft 54. The shaft 54 'which is supported in bearing blocks at 55,

56 and 57 is provided with a crank 58 to which a connecting rod 60 is pivoted to the pin 59. A link 63 is supported in a bracket 62 fixed to the girder 61 (see Fig. 3).. The link 63 carries a weighted lever 64 pivoted to its pin 65, and this lever is connected through the pin 66 to the connecting rod 60. A forked end 67 on the lever 64 embraces the rod 68, which is guided in supports 69 so as to be slidable and rotatable therein. The rod or pillar 68 is provided with two collars 70, 71, against which the forked end of the lever 64 engages toward the end of its upward and downward movements, so that the standard 68 moves with the fork 67 during these end movements.

A pin 72 (see Fig.7) projects from the guide 69 inwardly to move in a groove 73 of helical form. The groove 73 is formed on the standard 68. In this way the standard 68 in moving upwardly or downwardly is caused to rotate through an angle of about 180 so that the elevating arms 74 carried by the standard 68 may move from the full line position shown in Fig. 6 to the dotted line position 7 4 also shown in this figure.

The parts described constitute the elevating mechanism for removing the casks from the rotatable transporting table and it will be seen that the mechanism for operating the transporting table and the mechanism described for lifting the'casks from the table are both operated by the common driving member, namely the crank 30 with pin 31 which operates the two mechanisms alternately in an intermittent manner. Alongside the elevating device described there is arranged a receptacle 76 for receiving the hot pitch or like material with which the interiors of the casks are to be coated. This receptacle containing hot pitch may be of any known design. The hot receptacle contains a pressure reservoir 77 which may be placed in communication with the interior space of the receptacle 76 by means of a valve 7 8'or' may be cut out of communication by the same organ. The mechanism for regulating these operations consists of a lever 80 which is rotatable about a pin 79. The lever '80 is operated by a connecting rod 81 connected at 82 to a lever 83. A pin 84 operated by means of a lever 88, 88 rotatable about its pivot87' (see Fig. 5). The

arm 88' terminates in a slot 89 in which .a

pin 90 on the rod 91 operates. This rod is slidably mounted in guides 92 and carries rigidly connected therewith, a pin 93 against which there works a spring 94. The spring has the tendency to press the pin. 93 and the rod 91 downward. The rod 91 is provided at its lower end with a roller 95 which rests on a cam 96 mounted on the shaft 54. The air pressure pipe 97 terminates in the holder 77 and a cock 98 is inter, osed in this pressure pipe. The barrel 0 this cock is fixed to rotate with a rod 99. This rod has mounted on its end, a weighted lever 100 (see Fig.

4) which has the tendency to retain the cock- .in its closed position. The opposite rotaits bung hole over the spraying nozzle 107 through an angle.

102 which is mounted in guides 101. The rod 102 is operated upon by a cam 103 mounted on the shaft 54. The canting lever 83 forms a track for the barrel or cask removed from the coating device and this canting lever connects to'a track 104 which in turn leads to a transporting conveyer chain 105.

The operation of this device is as followsz-The hot gases pass through pipes 19 to the corresponding nozzles 21, and thereby enter the interior of the casks where the heat of the air causes the melting of the pitch or like coating on the interior surfaces. The melted pitch or the like flows through the bung holes or like openings 106 of the casks and passes intothe boxes 22, while smoke and vapor pass off through the conduit 24. At each complete rotation of the crank 30 the disk 34 and consequently the furnace and the transporting table move In this way a cask, say the cask 48 which has had the interior coating removed therefrom, passes into the position 48 At this position, the elevating and transporting arm 7 4 raises the cask or the like from the position 48 into the position 48 and at the same time .rotates through an angle of 180, until it arrives' in the position 74 shown in dotted lines in Fig. 6. In this position the cask is set with of the. coating device, that is to say, in the position 48 This movement is transmitted to the transportingand elevating arm by v the other motive element, namely the disk 35 which transmits its intermittent movement through the wheels 49, 50, 52, 53 and the crank 58. As soon as the cask is laid in position overthe spraying nozzle, the rod 68 is moved downwardly, whereupon the arm71 swings back into the position shown in full lines in Fig. 1. 1 At the same time,

' that is to say as soon as the cask is in position over the spraying nozzle 107, the cam 103, Fig. 4:, cooperates with the rod 102 whereby the weighted lever 100 is raised and the rod 99 with the barrel of the cock is moved into the open position. In this open posit1on the compressed air asses through the pipe 97 into the holder 7 and thereby presses the pitch or like coating substance in the receptacle 77 through the pipe 108 to the spraying nozzle 107, whereby the interior surface of the cask is coated. As soon as the cam liberates the rod 102, the lever under the influence of the weighted lever falls downward and closes the cook 98, and immediately thereafter the cam 96 engages the roller 95 of the rod 91. In this way the rod 91 is raised and also the lever 88 Fig. 5, is caused to rotate in a clockwise direction. This movement causes the lever 85, Fig. 1, also to swing in a clockwise di rection, whereby the operating lever or track 83 on which the receptacle or cask is mounted is raised into the position indicated by the line'83'. The cask then rolls downward over the operating lever 83 and rail 104' intothe dotted osition 48 where it is taken up and moved forward by the transporter 105. The canting lever 83 falls back by the weight of its right hand end in Fig. 1-, il'tfo tli position in full liti', whereb the receptacle 77 is again placed out of communication with the interior of the pitch or like receptacle 76. This is in virtue of the rod 81 being connected to the lever 83 on the left hand side ofthe pivot 82 Fig. 1.

It will be understood thatthe above described details may be varied within certain limits without departing from the nature of this invention.
